STOVE-LINING.

SPECIFICATION foriining part of Letters Patent no. 698,805, dated April29, 1902. Original application filed December 14, 1899, Serial No.740,313. Divided and this application filed March 16, 1901. Serial ToctZZ whom it may OOH/06772;.

Be it known that I, EDWIN R. CAHOONE, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented new and useful Improvements in Stove-Linings, of which thefollowing is a specification.

This invention relates to improvements in linings for fire-pots forstoves, and more especially to linings of a portable nature, and forms adivision of my application for patent filed December 14, 1899, SerialNo. 740,313. 7

The object of this invention is to provide a lining composed of a seriesof sections mounted side by side, whereby any individual part may bequickly and easily repaired.

A further object of this invention is to provide a series of portablebars forming a lining having air-heating chambers therein andexit-openings in the edges, which make com.- Inunication between saidchambers, a source of supply, and the fire-pot.

Many other objects and advantages will be hereinafter referred to and beparticularly pointed out in the claims.

Referring to the drawings forming a part of this specification, Figure 1is a perspective view of two portable sections of, my improved lining.Fig. 2 is'a side elevation of one section. Fig. 3 is a frontview of thesame, parts being broken away. Fig. 4 is a detail crosssection showingthe arrangement of the sections when placed side by side. Fig. 5 is avertical section showing the application of my invention and the meansemployed for heating water in connection therewith. Fig. 6 is a sideview of a modified construction.

In the drawings, 1 indicates a portable bar or section of lining, whichis composed of a rear flange or base 2; 3, a web connecting said fiangewith the front face portion 4, said face portion being grooved, as at 5,to prevent the coal from packing. Between the front 4 and the base 2 areformed, when two or more bars or sections are placed side by side,air-heating chambers 6, closed at the top by the head 7 and preferablyopen at the lower ends. The base 2 of each section extends on one side 8quite a distance behind and overlaps the edge of the adjoining sections,both edges of the (No model.)

sections being provided withya series of up wardly-inclined notches 9.By inclining the notches the fuel will not enter the chambers 6. Thehead 7 projects rearwardly from the base 2 and is connected to said baseby a web 10, the web having a notch forming a seat to rest on the wall11 of the stove, this position being further maintained by a web or lug12,

projecting rearwardly at a point approximately at the lower end of thebase, forming an air-heating flue between the sections and thestove-wall. Inthe'head 7 and on opposite sides thereof is a notch 13 anda lug 14, the lug on the adjacent section fitting the notch of itscompanion.

My invention is particularly well adapted for the application of awater-back, and one way of applying it in this connection isdisclosedin-Fig. 5.

15 represents the water-back, located so as to have all of its sidessubjected to the heat as it ascends to the exit, enabling me to obtainheated water in acomparatively short time.

In the modification disclosed in Fig. 6 the web 3 and lug 12 are eachdispensed with, and a chamber is formed betweeneach section and itssupport.

The operation of myinvention is as follows: The bars or sections aredropped in position on suitable supports in the fire-pot, the edges "ofthe base 2 of each section overlapping the opposite edges of theadjacent sections, and the lug 14 fits itsrespective notch 13, as shownin Figs. 1 and 4. Hence it will be seen that the-lugs 14 position thesections, while the overlapping edges'of the bases form a wedgingaction, which securely locks the sections together. The notches 9 ofeach adjacent section coincide with each other,forming a means of egressand ingress for the flames. The heads 7 fit close to each other, Whilethe re mainder of the fronts do -not touch, forming a vertical slotbetween each section for introducing the heated air to the fire-pot. Theair enters the air-heating flue 8 at the bottom, becomes highly heated,and passes through the exit-openings formed by the notches 9 in theedges of the portable sections into the airchambers 6 in said sections.I As the air passes into the chambers 6 it becomes broken and is mademore susceptible to a mixing action with the products of combustion,andin this heated condition it enters the fire-pot.

My invention is extremely simple in construction.

It is thought the utility of my invention will be readily comprehended.Suppose a portion of the lining of the stove should require repairs. Theparticular bar or section would be removed, and a new one or more, asthe case may be, could be quickly and readily substituted by anyattendant having ordinary intelligence.

Having thus fully described my invention, what I claim is- 1. Afire-potlining comprising a series of portable sections,each section having alug on one side and a notch on its opposite side, and anoutwardly-projecting flange on each side one of which is wider than theother, the lug of one section fitting the notch of the adjoiningsection, and the widest flange of one section overlapping the narrowflange of the adjoining section thereby locking and positioning thesections together when assembled.

2. A fire-pot lining comprising a series of portable sections, eachsection having a front portion and a base spaced from each other,

said base having its edges notched, one side of said base extendingbeyond the line of the edge of the front portion and adapted to overlapthe base of an adjoining section, the

'notches in the base registering to form airexits, whereby air may beintroduced to the fire-pot, means for spacing apart the front portionsof the adjoining sections, and means for securing the sections together.

3. A fire-pot lining comprising a series of portable sections, eachsection having a front portion and a base,means connecting the frontportion and base, the front portion, the base and the means connectingthe same form, with adjoining sections, when assembled airchambers, anda head which is slightly wider than the front portion whereby a space isformed between two adjoining sections below the head to form exits forair to pass to the fire-pot, air-heatin g chambers communicating withsaid spaces, and means for holding the sections together.

4. A section for a fire-pot lining, comprising a front portion, a base,and a web connecting the front portion and base, said base beingprovided with notches along its side edges adapted to be brought intoalinement with notches of adjacent sections of a fire-pot, said sectionalso comprising means for spacing it from adjacent sections and from thefire-pot, whereby air may be heated and introduced into thecombustion-chamber through the spaces formed between adjacent sectionswhen assembled.

5. A fire-pot lining, comprising portable sections, having a frontportion, a base having its edges notched, and a web connecting the frontportion and base, air-heating cham bers being formed between thesections when placed side by side, means for spacing. the sections, toform exits from said chambers, and air-heating chambers also beingformed between the fire-pot and portable sections,- said air heatingchambers communicating through the notches in the base with theaforesaid air-heating chambers formed between the adjoining sections.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
